When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0028] See also Figures 1 to 8 In an embodiment of the present invention, an experimental device for repairing groundwater pollution is provided, and the experimental device for repairing groundwater pollution comprises:

[0029] A base 1 and a fixing plate 2 fixedly mounted on the base 1, wherein a material storage barrel 22 is fixed on the fixing plate 2, wherein the material storage barrel 22 is used to hold medicines required for groundwater treatment;

[0030] A limiting sleeve 21 is fixed at the bottom of the storage barrel 22, and a guide pipe 20 for conveying medicines is movably installed in the limiting sleeve 21. The guide pipe 20 is provided with a plurality of through holes arranged at equal intervals. The guide pipe 20 is connected to a reciprocating mechanism arranged on the fixed plate 2 through a receiving plate 19. The reciprocating mechanism includes a slide groove 8 provided on the adjusting mechanism, and a sliding block 9 is slidably installed in the slide groove 8. A protrusion 10 and a fixed block abutting against the driving assembly are respectively fixedly installed on both sides of the sliding block 9. A guide assembly connected with the protrusion 10 is provided on the fixed plate 2, and the guide assembly is fixedly connected to the receiving plate 19, wherein the guide assembly includes a guide rod 17 fixedly installed on the fixed plate 2 and symmetrically arranged, a guide sleeve 18 movably installed on the guide rod 17, and a movable plate 16 fixedly installed between the two guide sleeves 18 and provided with a slot, and the movable plate 16 is engaged with the protrusion 10 and fixedly connected to the receiving plate 19.

[0031] See also Figure 1-3 , Figure 5-6 It should be noted that when placing medicines in the storage barrel 22, in the initial state, the through hole of the guide tube 20 is located outside the storage barrel 22. At this time, the material in the storage barrel 22 cannot be discharged through the through hole. When the driving component is working, the sliding block 9 is driven to slide in the slide groove 8, thereby driving the protrusion 10 to move. Since the protrusion 10 is engaged with the card slot, the movable plate 16 moves. Under the action of the movable plate 16, the guide sleeve 18 is driven to move along the length direction of the guide rod 17, thereby driving the receiving plate 19 along the length direction of the guide rod 17. Movement allows the guide tube 20 to enter the material storage barrel 22. When the through hole opened in the guide tube 20 enters the material storage barrel 22, the medicine in the material storage barrel 22 will enter the guide tube 20 through the through hole and be discharged through the guide tube 20. When the receiving plate 19 moves toward the base 1, the through hole is separated from the material storage barrel 22, and the medicine is no longer discharged. When the medicine is transported through the guide tube 20, the limiting sleeve 21 can prevent the medicine from being discharged from the through hole that is not placed in the material storage barrel 22, so as to ensure that the medicine is transported to the specified position.

[0032] The receiving plate 19 is fixedly connected to the reciprocating mechanism and the material guiding tube 20, and the fixed plate 2 is provided with an adjusting mechanism connected with the reciprocating mechanism, and the adjusting mechanism includes a hollow rod 6 rotatably mounted on the fixed plate 2, and a turntable 7 is fixed on the hollow rod 6, and a plurality of groups of fixed rods 11 equidistantly arranged in a circle are fixed on the turntable 7, and a toothing assembly connected with the fixed rod 11 is also provided on the fixed plate 2, and the toothing assembly is connected with the driving assembly, and the slide groove 8 is opened on the turntable 7, and the toothing assembly includes an incomplete gear 12 fixedly mounted on the driving assembly, a No. 1 rotating rod 14 rotatably mounted on the fixed plate 2, and a complete gear 13 fixedly mounted on the No. 1 rotating rod 14 and intermittently meshing with the incomplete gear 12, and a limit rod 15 intermittently abutting against the fixed rod 11 is also fixed on the No. 1 rotating rod 14.

[0033] See also Figure 1-2 , Figure 4-7 Furthermore, there are multiple groups of through holes. When the number of through holes entering the storage barrel 22 is different, the amount of material discharged is also different. Therefore, it is necessary to adjust the angle of the turntable 7 to change the angle of the slide slot 8 relative to the horizontal axis. In the initial state, the angle of the slide slot 8 relative to the horizontal axis is zero. When the driving component is working, it drives the sliding block 9 to rotate. At the same time, it also drives the incomplete gear 12 to rotate. The incomplete gear 12 has teeth and no teeth. At this time, the toothed part meshes with the complete gear 13 and drives the complete gear 13 to rotate, thereby driving the No. 1 rotating rod 14 to rotate, so that the limit rod 15 rotates. When the limit rod 15 is working, the gear 13 is engaged with the complete gear 13, and the gear 13 is driven to rotate. The fixed rod 11 abutting against it is driven to move, so that the turntable 7 rotates a certain angle, so that the angle of the slide groove 8 changes, thereby changing the movement trajectory of the protrusion 10, and making the receiving plate 19 reciprocate in the vertical direction. At this time, the number of through holes entering the storage barrel 22 is the least, and when the toothed part is separated from the complete gear 13, the complete gear 13 just rotates one circle, and the toothless part faces the complete gear 13, and the complete gear 13 stops rotating, and the above steps are repeated, so as to achieve the purpose of gradually increasing the amount of material unloading each time, wherein the hollow rod 6 is provided with damping to ensure that the sliding block 9 will not drive the turntable 7 to rotate when it moves.

[0034] The fixed plate 2 is also provided with a driving assembly for driving the adjustment mechanism and the reciprocating mechanism to move, and the driving assembly includes a motor 3 fixedly mounted on the fixed plate 2, a transmission rod 4 rotatably mounted on the fixed plate 2 and connected to the output shaft of the motor 3, and an eccentric wheel 5 fixedly mounted on the transmission rod 4 and abutting against the protrusion 10 and the limit block. The transmission rod 4 is fixedly connected to the incomplete gear 12 and connected to the intermittent transmission mechanism.

[0035] See also Figure 4-5Furthermore, when an experiment is needed, the motor 3 works to drive the transmission rod 4 to rotate, thereby driving the eccentric wheel 5 to rotate. Since the eccentric wheel 5 is in contact with the limit block and the protrusion 10, and the eccentric wheel 5 is eccentrically arranged, under the action of the eccentric wheel 5, the sliding block 9 is driven to move. At the same time, the transmission rod 4 will also drive the incomplete gear 12 to rotate, thereby realizing material unloading. The transmission rod 4 will also drive the intermittent transmission mechanism to move.

[0036] An intermittent transmission mechanism connected to the driving assembly is provided on the base 1, and the intermittent transmission mechanism includes a No. 1 bevel gear 24 rotatably mounted on the fixed plate 2, a No. 1 belt 23 sleeved on the transmission rod 4 and connected to the rotating shaft of the No. 1 bevel gear 24, and a Maltese cross movement assembly provided on the base 1 and connected to the receiving assembly, and a No. 2 bevel gear 25 meshing with the No. 1 bevel gear 24 is fixed on the Maltese cross movement assembly, wherein the Maltese cross movement assembly includes a No. 2 rotating rod 26 rotatably mounted on the base 1, a driving wheel 27 fixedly mounted on the No. 2 rotating rod 26, and a driven wheel 28 fixedly mounted on the receiving assembly and cooperating with the driving wheel 27, and the No. 2 rotating rod 26 is fixedly connected to the No. 2 bevel gear 25.

[0037] See also Figure 4-5 , Figure 8 , further speaking, when the transmission rod 4 rotates, the No. 1 bevel gear 24 is driven to rotate through the No. 1 belt 23, and the No. 2 bevel gear 25 in meshing is driven to rotate, thereby driving the No. 2 rotating rod 26 to rotate. When the No. 2 rotating rod 26 rotates, it drives the driving wheel 27 to rotate. Under the action of the driving wheel 27, the driven wheel 28 matched with it is driven to rotate intermittently, thereby driving the receiving component to move. Among them, when the transmission rod 4 rotates one circle, one material unloading will be completed. The first half circle is the material unloading time period, and the second half circle stops unloading. The driving wheel 27 will not drive the driven wheel 28 to rotate in the first half circle. In the second half circle, the driving wheel 27 drives the driven wheel 28 to rotate, and under the action of the driving wheel 27, the driven wheel 28 will not rotate a certain angle more due to inertia, thereby ensuring the accuracy of each transmission. Among them, when the transmission rod 4 rotates one circle, the driving wheel 27 also rotates one circle.

[0038] The base 1 is also provided with a receiving assembly connected to the intermittent transmission mechanism, on which a reagent bottle 33 for receiving the medicine transported by the guide tube 20 is placed. The receiving assembly includes a No. 3 rotating rod 29 rotatably mounted on the base 1 and fixedly connected to the driven wheel 28, a support rod 31 rotatably mounted on the base 1, and a support plate 32 fixedly mounted on the support rod 31 and with the reagent bottle 33 placed thereon. The No. 3 rotating rod 29 is sleeved with a No. 2 belt 30 connected to the support rod 31.

[0039] See also Figure 1-2 , Figure 4-5 Finally, in the initial state, the reagent bottles 33 are equidistantly arranged on the support plate 32, and the reagent bottles 33 are filled with groundwater that needs to be repaired. One of the reagent bottles 33 is located directly below the guide tube 20. When unloading, the medicine will be transported to the reagent bottle 33 located below the guide tube 20. At this time, when the driven wheel 28 rotates, it drives the No. 3 rotating rod 29 to rotate. The No. 3 rotating rod 29 will drive the support rod 31 connected to it to rotate through the No. 2 belt 30, so that the support plate 32 rotates, thereby driving the reagent bottle 33 without medicine to move to the bottom of the guide tube 20, so as to ensure that the unloading is transported to the reagent bottle 33 each time, and then observe the repair situation of the groundwater in each reagent bottle 33 according to the different unloading amounts, so as to experiment with the best amount of medicine.

[0040] Taking the embodiment combining all the features recorded in the present application as an example, when in use, medicines are placed in the storage barrel 22. In the initial state, one of the reagent bottles 33 is located directly below the guide tube 20, and the angle of the slide groove 8 compared to the horizontal axis is zero. When an experiment is needed, the motor 3 works to drive the transmission rod 4 to rotate, thereby driving the eccentric wheel 5 to rotate. Since the eccentric wheel 5 is in contact with the limit block and the protrusion 10, and the eccentric wheel 5 is eccentrically arranged, under the action of the eccentric wheel 5, the sliding block 9 is driven to slide in the slide groove 8, and the transmission rod 4 will also drive the incomplete gear 12 to rotate. The incomplete gear 12 has teeth in part and no teeth in part. At this time, the toothed part meshes with the complete gear 13 and drives the complete gear 13 to rotate, thereby driving the No. 1 rotating rod 14 to rotate, so that the limit rod 15 rotates. Under the action of the limit rod 15, the fixed rod 11 abutting therewith is driven to move, so that the turntable 7 rotates a certain angle, so that the angle of the slide groove 8 changes, thereby changing the movement trajectory of the protrusion 10. The protrusion 10 is engaged with the slot, so that the movable plate 16 moves. Under the action of the movable plate 16, the guide sleeve 18 is driven to move along the length direction of the guide rod 17, thereby driving the receiving plate 19 to move along the length direction of the guide rod 17, so that the guide tube 20 moves in When the through hole of the guide tube 20 enters the storage barrel 22, the medicine in the storage barrel 22 will enter the guide tube 20 through the through hole, and be discharged into the reagent bottle 33 through the guide tube 20. At this time, the amount of medicine entering the storage barrel 22 through the through hole is the least. When the toothed part is separated from the complete gear 13, the complete gear 13 just rotates one circle, and the toothless part faces the complete gear 13, and the complete gear 13 stops rotating. At the same time, when the movable rod 4 rotates, the first bevel gear 24 is driven to rotate through the first belt 23, and the second bevel gear 25 placed in meshing is driven to rotate, thereby driving the second rotating rod 2 6 rotates, when the No. 2 rotating rod 26 rotates, it drives the driving wheel 27 to rotate, and under the action of the driving wheel 27, the driven wheel 28 matched with it is driven to rotate intermittently. When the medicine falls into the reagent bottle 33, at this time, when the driven wheel 28 rotates, it drives the No. 3 rotating rod 29 to rotate, and the No. 3 rotating rod 29 will drive the supporting rod 31 connected to it to rotate through the No. 2 belt 30, so that the supporting plate 32 rotates, thereby driving the reagent bottle 33 without medicine to move to the bottom of the guide tube 20, so as to ensure that the unloaded material is transported to the reagent bottle 33 each time, and repeat the above steps, so as to achieve the effect of gradually increasing the amount of unloaded material each time.

[0041] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
